March 2026: The Hottest New Costco Items You Should Grab

There's little else that revs our engines quite like fresh Costco finds that perfectly suit our busy lifestyles. Sure, we got excited when we found out you could buy a whole barrel of maple syrup at certain Canadian outlets (hello, world pancake domination!), but our personal must-haves when browsing the Costco aisles are a bit more pedestrian. Give us a great deal on sports drinks, a two-pack of avocado mayo, or chocolates flavored like Girl Scout cookies, and we're happy campers. Catch us pushing one of those giant carts, our low-cost food court drink strapped into an improvised cup holder, humming a jaunty tune as we load up on the hottest new items. 

March looks like another promising month for Costco-ites seeking new favorites to try and limited-time offers to scoop up. From classic kitchen tools to craveable snacks, we're loving all the new-new that Costco's showing off. As is always the case, prices and availability on all items listed are subject to change and may vary based on location.

Orange juice may be more hydrating than water, but an Orange Swirl Prime drink is just what the doctor ordered when you're thirsty. Hotter days are coming, so now is the time to stock up on these limited-edition hydration drinks. They're as cooling after kids' sports practices as they are your own sweaty morning run. These will also make your delivery person from UPS or Amazon happy if you leave them in a mini-fridge by the front door!

Purchase PRIME Hydration Drink, Limited Edition Variety Pack for $19.99. 

There's a difference between mayo and aioli, but, for all intents and purposes, there is no distinction between "regular" mayo and mayo made with avocado oil. That is, except for the fact that the latter is made without seed oils (a hot-button health issue as of late) and, in the case of Chosen Foods' mayo, uses cage-free eggs. You'll want to use this slightly more health-conscious, keto-friendly spread everywhere that you normally use plain jane mayo.

Purchase Chosen Foods Avocado Oil Classic Mayo 2-pack for $29.99.

We know why popular Girl Scouts cookie flavors get discontinued, but not always why we crave these treats all year long. In one oh-so-giftable box, you will have four different varieties of scrumptious chocolate treats based on favorite Girl Scouts cookies like Thin Mints and Lemon-Ups. "Bites" are tiny filled balls perfect for popping, and "Snappers" are bite-sized bits with drizzled topping. Neither are cookies shilled by adorable tykes with sashes, but they'll fill the void nicely until next winter. 

Purchase the Edward Marc Chocolatier GIRL SCOUTS Themed Gift Box for $49.99.

It isn't the most-caffeinated roast you can get at Starbucks, but we admit to loving the Siren's dark roasts. This generous variety pack of Starbucks K-cups will ensure that you have steamy-fresh coffee whenever and wherever you want it ... assuming "wherever you want it" includes a power outlet, of course. With 64 pods per box, this pack is perfect for fueling a waiting room Keurig, or simply one very thirsty family. 

Purchase the Starbucks Dark Roasts Variety Pack K-Cup Pod, 64-count for $47.99. 

The circus just came to Costco! We're referring, of course, to Barnum's Animals Crackers, that childhood snack spanning generations that's shaped like the wildlife of a cheerful menagerie. There are 30 packs of crackers in one of these value-sized boxes, making it the perfect stock-up stash for parents of toddlers ... or simply those who are in touch with their inner kiddo. There's a right time to add milk to tea; how about a right time to add cookies to milk? Let's experiment! 

Purchase BARNUM'S Animal Crackers, 1 oz, 30-count for $12.49. 

Martha Stewart seasons her cast iron with Crisco, but there's no worry about breaking in this double-sided griddle ... it comes to you pre-seasoned with vegetable oil, meaning it's ready to cook. For less than a 50-spot, you can invest in a durable piece for your kitchen that, if cared for with the bare minimum of attention, will last for generations. Who says that you have to brave the elements for perfect grill marks? Just turn on your burners and set this griddle on your stovetop.

Purchase the Lodge Cast Iron Reversible Grill/Griddle for $39.99. 

Keto-certified! High fiber! Low calorie! No seed oils! The buzzy benefits of these humble tortillas are so numerous that they might, conceivably, be called "xtreme." Whether or not they're edible is up for debate — Costco shoppers avoid the similar-ish low-carb BFree tortillas like the plague. Hope springs eternal, however, and we're super intrigued by the concept of a delicious tortilla that might satisfy those of us watching our macros. We'll be trying them with fajita chicken and plenty of veggies. 

Purchase Olé Mexican Foods 8" Xtreme Wellness Tortilla Wraps for $8.79.

We're a sucker for pretty glassware at a great price, and the Preston set by Libbey fits the bill. There are eight tall tumblers and eight short tumblers, ensuring that you have ample drinking glasses for family and friends alike. The simple elegance of the design has timeless appeal — we think these glasses will look as great beside your holiday feasts as weeknight takeout. Don't forget to read up on the right way to store your drinking glasses!

Purchase the Libbey Preston Drinkware Glass Set for $27.99.

When we rounded up the best new snacks of 2025, spicy flavors dominated the "savory" column. It shouldn't surprise us that Chomps, a beef stick brand we already love, has a kickin' jalapeño flavor, but we're sure glad it does. Made of grass-fed and finished beef, with zero sugar and 10 grams of protein, this is a nibble you can feel good about when you get that all-too-human urge to snap into a Slim Jim. (Okay, maybe we're dating ourselves?)

Purchase Chomps Jalapeno Grass Fed Beef Sticks for $21.99.
